UNITED STATES FREEMAN B. PRICE, OF BUTTE, MONTANA.

COFFEE-PERGOLATOR.

Specification of Letters Patent.

Patented Sept. 24, 1907,

Application filed December 19,1906. Serial No. 348,646.

To all whom it may concern:

Be it known that I, FREEMAN B. PRICE, a citizen of the United States,residing at Butte, in the county of Silverbow and State of Montana, haveinvented a new and useful Improvement in a Coffee-Percolator, of whichthe following is a specification.

This invention relates to a percolator intended for use with coffee urnand the object of the invention is a device of this kind which willpreserve the aroma of the coffee and will prevent the filter paperthrough which the coffee is filtered from becoming clogged either by theweight of the coffee bearing directly upon it thereby saturating thefilter paper with coffee grounds or becoming coated with albumen whenthe egg is broken into the coffee for the purpose of enriching it incolor.

The invention consists of the novel features hereinafter describedpointed out in the claims and shown in the accompanying drawings, inwhich,

Figure 1 is a side elevation of my device in position upon a coffee urn.Fig. 2 is a vertical section through the percolator casing showing theposition of the same,

. while the coffee is being prepared. Fig. 3 is a view of the percolatorpartly in side elevation and partly in section showing the strainer,filter paper and perforated cap in position ready for inversion of thepercolator. Fig. 4 is a perspective view showing the various partsdetached.

In these drawings A represents a cylindrical receptacle having acontracted upper portion which when the receptacle is inverted restsupon the top of a coffee urn of the usual kind.

The receptacle A is provided with a bail A and also upon one side and atits lower edge with a handle A Extending vertically up the side of thereceptacle A is a tube A which opens inwardly at its lower end as shownat A and at its upper end opens into the outer air as shown at A Uponthe neck portion of the receptacle are placed a plurality of inwardlyextending lugs A and outwardly extending lugs A In connection with thisreceptacle I employ a disk B, of any suitable filter paper and aperforated pan (3. I also provide a cap D having a perforated top and anannular fiange D and having bayonet slots D cut therein. I also providea non-perforated cover E shown in Fig. 2. The percolator is alsoprovided with a faucet A carried by the casing A.

In use the coffee is prepared in the usual manner by boiling in thereceptacle A, the top of which is closed by the cover E. When the coffeehas been boiled a sufficient length of time, the'cover E, is removed andthe pan 0 is dropped into the receptacle A and is held in the neck ofthe receptacle by the lugs A. The filter paper B is then dropped into-place upon the pan 0 and the cap D is placed upon the receptacle and islocked into position by engage,

ment of the lugs A with the slots D The receptacle A is then placed uponan urn F in a vertical position as shown in Fig. l. The coffeepercolates through the perforations of the pan G through the filterpaper B and through the cap D.

It will be obvious that when in an inverted position, the pan 0 willhold the coffee grounds, and also the egg if one is used out of contactwith the filter paper thus keeping'the same free from sediment andpreventing it becoming clogged or in an unsanitary condition, insuringclearness of the coffee. The filter paper it will be obvious is heldwhen the receptacle is inverted between the pan 0 and the perforated capD.

The faucet A can be employed both for drawing off coffee from thereceptacle, or if after the receptacle is inverted the coffee is toostrong boiling water can be introduced into the receptacle A through thefaucet A in the manner illustrated in Fig. l.

The device is especially adapted for the making of coffee upon a largescale as the holding of the coffee grounds out of contact with thefilter paper increases the quantity filtered in a given time.

The tube A furnishes an exit for steam and air when the receptacle is inits normal position and in its inverted position permits inward flow ofair to occupy the space vacated by the liquid as it percolatcs throughthe filter paper.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent,

ist-

A device of the kind described comprising a receptacle, said receptaclehaving a contracted neck portion, inwardly and outwardly extending lugsformed on said neck portion, a perforated pan fitting within the neckportion and engaged by the inwardly extending lugs, a filter paperresting upon said pan when the receptacle is in its normal position,anda cap adapted to tightly fit over the neck portion, said cap having aperforated top and having slots adapted to engage the outwardlyextending lugs.
